We divide 436446 by 80
We want to divide 436446 by 80.

Step 1:
The number 80 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 80

Advancing to step 2:
80 can be fit into 43 0 times, resulting in a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 43, we end up with 43.
Grab the next digit (6) from the dividend, add it to 43, then carry on: 436 / 80

Advancing to step 3:
436 divided by 80 is 5 with a remainder of 36.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we take 400 away from 436, we end up with 36.
Append the next digit (4) from the dividend to 36 and continue with: 364 / 80

Let's proceed to step 4:
80 can be fit into 364 4 times, resulting in a remainder of 44.
Record the quotient 4 as the next digit in the result. 
Result so far: 54.0
If we take 320 away from 364, we end up with 44.
Grab the next digit (4) from the dividend, add it to 44, then carry on: 444 / 80

Advancing to step 5:
When dividing 444 by 80, we get 5 with a remainder of 44.
Use 5 as the next digit of our solution. 
Result so far: 545.0
The remainder is 44 after subtracting 400 from 444.
Fetch the next digit (6) from the dividend, attach it to 44 and continue: 446 / 80

Advancing to step 6:
When dividing 446 by 80, we get 5 with a remainder of 46.
Record the quotient 5 as the next digit in the result. 
Result so far: 5455.0
The remainder is 46 after subtracting 400 from 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 7:
80 goes into 460 5 times with a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 5455.5
If we subtract 400 from 460, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 8:
80 goes into 600 7 times with a remainder of 40.
The next digit of our result is 7. 
Result so far: 5455.57
Subtracting 560 from 600 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 9:
400 divided by 80 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 5455.575
The remainder is 0 after subtracting 400 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
0 divided by 80 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 5455.575
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 11:
If we divide 0 by 80, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 5455.575
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 5455.575, with a leftover of 0.0.
